ABSTRACT:
A large diameter pipe joint in which the male end and the female mouth end have respective opposite load bearing surfaces 5, 22 between which are arranged bracing means capable of evenly distributing tensile forces over the whole periphery of the joint by means of an incompressible mass 27 of an initially fluid filler material. The mass is contained in a space sufficiently closed on all sides by an annular component 23 disposed between the two support surfaces 5, 22 to be impermeable to said filler material. This joint is particularly suitable for large diameter pipes laid in trenches, where the axes of adjacent pipe sections lie at a small acute angle to each other after installation.
